1. Help Reduce Inflammation

Pumpkin seeds contain omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which may help reduce chronic inflammation.

One study found that a mixture of pumpkin, flax, and sesame seeds reduced inflammatory markers in adults with liver disease.

Pumpkin seeds also make a healthy topping for salads or smoothies.

2. Support Heart Health

Pumpkin seeds contain nutrients that promote cardiovascular health.

Benefits include:

ALA omega-3 fatty acids that support heart function.
Magnesium and potassium, which help regulate blood pressure.
Antioxidants that help protect blood vessels.

Several studies suggest that regular seed consumption is associated with healthier blood pressure levels.

3. May Help Manage Diabetes

Pumpkin seeds may help improve blood sugar control.

Animal studies suggest pumpkin seed extract has anti-diabetic properties, while human research indicates the nutrients found in pumpkin seeds may help maintain healthy blood glucose levels.

Combining pumpkin seeds with flaxseeds may also help reduce diabetes-related kidney complications.

4. Promote Better Sleep

Pumpkin seeds are a natural source of tryptophan, an amino acid involved in producing serotonin and melatonin.

Studies suggest that adequate tryptophan intake may:

Improve sleep quality.
Help people fall asleep faster.
Support healthy sleep cycles.

Eating a small serving of pumpkin seeds in the evening may contribute to better sleep.

5. Support Eye Health

Pumpkin seeds provide zinc, lutein, and zeaxanthin, nutrients essential for maintaining healthy vision.

A 28 g serving supplies approximately 19% of your daily zinc needs.

Pumpkin seed oil also contains lutein and zeaxanthin, antioxidants associated with protecting against age-related eye conditions.

6. May Improve Prostate Health

Research suggests pumpkin seeds and pumpkin seed oil may help reduce symptoms of benign prostatic hyperplasia (BPH).

Pumpkin seed supplements are commonly included in natural prostate health products and may help improve urinary function.

7. May Help Prevent Urinary Tract Stones

Some research indicates that regular pumpkin seed consumption may help reduce the formation of mineral deposits in the urinary tract, supporting bladder health.

8. Have Anti-Parasitic Properties

Several studies suggest pumpkin seeds may help eliminate certain intestinal parasites.

One clinical study reported a significant reduction in parasite load after participants regularly consumed pumpkin seeds.

9. May Support Weight Management

Although no direct evidence shows pumpkin seeds cause weight loss, they are rich in protein and fiber, helping promote fullness and reduce unhealthy snacking when eaten in moderation.

10. Contain Compounds With Anticancer Potential

Pumpkin seeds contain phytoestrogens and antioxidants that researchers continue to study for their potential role in reducing the risk of certain cancers, particularly breast cancer.

Current evidence is promising but remains preliminary, and pumpkin seeds should not be considered a cancer treatment.
